Circuit for reducing line harmonics in the input current of a diode rectifier

摘要

Circuit arrangement (1) for reducing the harmonics of the input current of a rectifier (10) connected to an AC network (N) to provide a DC voltage for a DC load (40) having a storage capacitor (C _ZK ) comprising a DC voltage adjuster connected downstream of the rectifier (10) (20) and a controller (30) configured to impart a specific current to the DC voltage controller (20), in particular to impart a harmonic current signal approximating the shape of the DC current so as to reduce the harmonic content in the input current.
